I’ve this issue since a long time, also with previous ZB 3.xx Mac versions: it happens, quite often (say 2 or 3 times in 1 hour session), that if I pan or zoom the model in the viewport, ZB crashes instantly.
I never figured out what could cause it: it’s not due to mesh complexity (it happens also with a 1000 polygons tool), it happens using mouse or tablet as well.
Also, it happens both in Leopard and Snow Leopard, and both on my Mac Pro and my MacBook Pro…
Reinstalled on both several times and still the problem occurs …
So I’m quite clueless, I think I’m opening a support ticket, but I just wanted to know if some of you are experiencing the same issue …
